From the Heritage Rail Alliance schedule of presentations for the Spring Symposium:

"HeritageRail and Education. The session will explore to following: How to use your collection as a teaching tool and become an educational resource; Building relationships with local schools; Fulfilling state requirements for public schools; Basics of field trips; Outreach into schools; Special needs programs; Partnering with other museums; and education and fundraising."

If those associated with non-profits were to look at the documents under which their organization was established and their 501(c)(3) application, you may well find that the justification for the non-profit status is education.

This is true for the Engine 557 Restoration Company. For this reason, I try and regularly include an educational component in posts on our Facebook page and we welcome visitors (including Boy Scout and home school groups) to our Engine House restoration facility.
